Technical Metadata

The Technical Metadata view displays information about each file (in either a CSV document or a table) including the file size, metadata from the <fmt > chunk, the existence of key metadata chunks, and file warnings.

Value Name

Description

FileName

In order to provide a concise presentation the filepaths are displayed from the directory path where the files diverge. Thus if two files are opened from /HardDrive1/videofiles/movies/videofile.avi and /HardDrive1/videofiles/spokenword/videofileB.avi then these will be displayed in the table view as /movies/videofile.avi and /spokenword/videofileB.avi since the /HardDrive1/videofiles section of the Filepath is common to the open files.
The CSV version of the Technical Metadata view displays the full filepath to each file.

FileSize

The size of the video file in bytes.

Format

This value represents the type of container utilized by the file, including profile information. Example: AVI (OpenDML).

Duration

The total playing time, displayed in HH:MM:SS.mmm (hours, minutes, seconds, milliseconds)

Vid Format

The name of the codec used to encode the video data.

Vid CodecID

The four character code (fourCC) used by the AVI container to describe the video codec. This value is presented in ASCII characters. Below is a sample of compression codes:

dvsd

DV 25 Mbps

DV50

DV 50 Mbps

H264

H.264

IV30

Indeo

JFIF

JPEG

LJ2K

JPEG 2000

MP41

MPEG-4 Visual

v210

YUV 10 bit

Vid FrameRate

The amount of frames per second intended for presentation on playback of the file.

Vid Width

The number of pixel columns within the frames of the video stream.

Vid Height

The number of pixel rows within the frames of the video stream.

Vid BitDepth

The number of bits of data per channel per pixel that the video data will decode to.

Vid BitRate

A measurement in bits per second for the video stream.

Aud Format

The name of the codec used to encode the audio data.

Aud Format

The two character code (twoCC) used by the AVI container to describe the audio codec. This value is presented in hexadecimal representation. Below is a sample of compression codes:

0000

Unknown

0001

PCM / Uncompressed

0002

Microsoft ADPCM

0006

ITU G.711 a-law

0007

ITU G.711 Aµ-law

0011

IMA ADPCM

0016

ITU G.723 ADPCM (Yamaha)

0031

GSM 6.10

0040

ITU G.721 ADPCM

0050

MPEG

FFFE

Extensible (used by Microsoft to provide a GUID as codec identifier)

FFFF

Experimental

Aud Channels

The number of audio channels encoded within the audio stream.

Aud SampleRate

The number of audio samples per second.

Aud BitRate

The number of bits utilized per second of audio.

Aud BitDepth

The number of bits of data per channel per sample that the audio data will decode to.

Tdat

Notes the existance of the Tdat chunk, either 'Yes' or 'No'. The tdat chunk is often used in Grass Valley and Adobe AVI applications.

INFO

Notes the existence of the INFO chunk, either 'Yes' or 'No'.

XMP

Notes the existence of the XMP chunk, either 'Yes' or 'No'. Right-click on this cell provides options to Import, Export, or Remove xml data. Doubling-clicking on the cell brings a text editor. Changes are not made until the file is saved.

aXML

Notes the existence of the aXML chunk, either 'Yes' or 'No'. Right-click on this cell provides options to Import, Export, or Remove xml data. Doubling-clicking on the cell brings a text editor. Changes are not made until the file is saved.

iXML

Notes the existence of the iXML chunk, either 'Yes' or 'No'. Right-click on this cell provides options to Import, Export, or Remove xml data. Doubling-clicking on the cell brings a text editor. Changes are not made until the file is saved.

MD5

If an MD5 chunk exists, this column will show the stored value. This MD5 value is a checksum of the stream data only and does not include the file's metadata or any other chunk.

MD5 evaluated

If the MD5 is evaluated it will appear in this column. Any conflict between this column and the 'MD5' column indicates a change in the stream data portion of the file between the current evaluation and the stored evaluation.

Errors

Provides statements about potential structural problems with a given audio files: for instance if the RIFF size statement conflicts with the actual file size or if the audio files does not utilize padding bytes to follow odd byte length chunks.
